Antenna Associates

What Antenna Associates does

Antenna Associates, Inc. is a Brockton, Massachusetts-based designer and manufacturer of specialized military and civil aviation antenna systems, founded in 1979 by two engineers and now operating as a subsidiary of Diamond Antenna and Microwave Corporation following its November 2025 acquisition. The company's product portfolio centers on six categories: IFF/SSR antennas (Identification Friend-or-Foe / Secondary Surveillance Radar, including the ESA22M electronically steered antenna launched in 2026), monopulse secondary surveillance radar (MSSR) antennas, ADS-B antennas, Honeywell-licensed altimeter antennas for AN/APN-209 and AN/APN-194 systems (the company is the sole licensed manufacturer), composite radomes and reflectors, and azimuth antenna positioners/rotators. Supporting services include custom antenna/system engineering, on-site testing at 120-ft and 650-ft outdoor ranges, and overhaul/refurbishment of legacy military equipment. The underlying technology relies on classical RF engineering and composite manufacturing (Kevlar, carbon fiber, high-strength glass with vacuum bagging, autoclaving, and lamination pressing), executed in a single 18,000 sq. ft. ISO 9001:2015-certified facility.

The company serves tier-1 US and allied defense prime contractors—including Lockheed Martin (AN/TPS-77 radar), Northrop Grumman (G/ATOR system), Raytheon (AN/UPX-37, AN/TPX-56/57), BAE Systems, Indra, Leonardo, Hensoldt, Elta, and Telephonics—alongside the US military across all branches, the FAA, and government aviation authorities in 30+ countries. Its antennas are deployed on the US Air Force's North Warning System, at more than 75 air traffic control stations globally, and on military vessels, mobile vehicles, and stationary radar sites.

Antenna Associates generates revenue through four streams: (1) hardware sales of standard and custom antennas plus complementary components (rotators, radomes, mounts, rotary joints, control units, cabling); (2) custom antenna engineering and design services leveraging CST, HFSS, Geostar, PDM Works, and SolidWorks; (3) antenna testing services with full confidentiality at competitive rates; and (4) overhaul, refurbishment, and reverse-engineering of legacy military antennas when OEMs have exited support. Pricing is quote-based with no public disclosure, sales are handled through direct enterprise engagement by named account managers (Dana Sandquist for products, Clement Frazier for testing), and the go-to-market is direct B2B with no third-party resellers or distribution channels.
